A clock system using PLL for high speed and low power parallel link is presented. The PLL is designed with a voltage regulator which provides a clear supply voltage for the noise sensitive blocks such as voltage controlled oscillator in the noisy environment. A new method is explored to generate clocks for dynamic frequency switching of the high speed link which works in source-synchronous style....
Considering the characteristics of mobile network, we import three important parameters: distribution density of mobile phone, coverage radius of Bluetooth signal and moving velocity of mobile phone to build an epidemic model of mobile phone virus which is different from the epidemic model of computer worm. Then analyzing different properties of this model with the change of parameters; discussing...
In this paper, two kinds of methods of calculating the hydrogen content of a-Si:H thin film by means of the wagging mode and the stretching modes of infrared-transmission spectra, are investigated. The reason for the difference in these two calculation results is analyzed. If the contents of SiH2 and (SiH2)n are indicated in terms of a structure factorF=(/840+/880)//2000,...
